CONSTITUTION: This image receiving element is used for thermal dye transfer and is composed of a support material, intermediate layer and image receiving layer and other layer as necessary, and the intermediate layer is made from a crosslinked material containing no organic solvent, and the image receiving layer is made from a non-crosslinked material containing no organic solvent. In this case, a crosslinked material of the intermediate layer is a crosslinked lacquer, and crosslinking is accomplished using high-energy radiation, electron beam, or UV ray for example. The intermediate layer is made from at least monomer, oligomer, and/or prepolymer. The intermediate layer is made without using organic solvents.

パルスは熱転写プリンターに伝達され、印刷ヘッドにお
いて熱に変換される。The thermal colorant transfer system (Dye Dispersion Thermal Transfer-D2T2) forms an image of a pattern by an electronic method. In this case, this pattern is decomposed into the primary colors: cyan, magenta and yellow and optionally black, which are converted into electrical impulses. This impulse is transmitted to the thermal transfer printer where it is converted to heat at the printhead.

像が生じる。The image receiving material passes through a thermal transfer printer in contact with the colorant-donor element. In the printhead, the backside of the colorant-donor element is heated to release the colorant, depending on the impulse predetermined range, and the colorant diffuses or sublimes into the receiving layer of the image receiving material. This step is passed through for all colorants in turn, producing a finished image.

している。It is known from Japanese Examined Patent Publication No. 60-236794 that the support material made of paper is coated with a thermoplastic high molecular weight material before the image receiving layer is coated. This high molecular weight thermoplastic is a polyolefin, polystyrene, polyvinylidene chloride, polyethylene-terephthalate, polymethylmethacrylate or ionomer resin. The unevenness of the paper surface is made uniform through the intermediate layer made of thermoplastics.

When processed at 60 ° C., it is preferred to use no monomer. This monomer, oligomer or prepolymer has a carbon double bond (> C = C <) as an acryl-, methacryl-, allyl- or vinyl compound. They may additionally contain hydroxyl groups, carboxyl groups and other polar groups, for example for improving the adhesion of the image-receiving layer.

Titanium dioxide is particularly advantageous because of its high refractive index. Lacquers containing up to 70% by weight of titanium dioxide have been successfully processed. Thereby, the image underground has a high light reflectance and the image looks clearer.

If UV lamps are used, a photoinitiator must be added to the lacquer in order to generate radicals which initiate the crosslinking reaction.

載されている。To produce a particularly sharp image, the lacquer is crosslinked by contacting it with a high-gloss metal surface, or a high-gloss cylinder, and irradiating it with high-energy electrons. Irradiation with accelerated electrons is then carried out from the back side, ie from the side not covered by the support material. The electrons must be accelerated so that their penetration depth exceeds the thickness of the support material plus the lacquer layer. This technique is described in DE 3022709.
